[DEBUTANT]_ pb de randomisation

Version imprimable

Bonjour !
Dans le code ci-dessous, je génère 2 types d'essais : 70 % de PS et 30 % de stop signal...Mon problème est que ces 2 types sont écrits consécutivement dans mon fichier texte alors que je souhaiterai mixer ces 2 types de façon randomisée...Si vous pouviez éclairer ma lanterne:oops:

par contre les globales c est mal, pour plusieurs raisons, tu devrais declarer les variables dans ton main et les passer en param des fonctions quand elles en ont besoin.

Voila, bon courage

si t as des questions hesite pas

:king:
super pour toutes ces corrections et améliorations :king:
Je ne ferme pas la discussion car je pars en congés et n'aurai pas le temps de tester ça tout de suite...
Mais encore un GROS MERCI;)

ok c'est vraiment parfait !
J'ai fait un sacré bon dans la compréhension grâce à tes corrections !
Cependant, je me pose encore une ptite question de randomisation...
Je voulais faire un random sur les chiffres entrés dans SSD_times(cf code)...ex : l'utilisateur saisi 3 SSD : 10 20 et 30...Je veux obtenir un rand de l'un de ces 3 nombres...
Si je fais rand () % SSD_times , cela me sort des nombres aléatoires dans la fourchette que l'utilisateur a saisi et moi je voudrai un random des nombres saisis...Si qqn a une idée...
Code:

1 2 3 4 5 6 7 8 9 10 11 12 while (looptrial<SSD_nb) { printf("Times of Stop Signal Delay (ms) ? : "); scanf("%d",&SSD_times); fprintf(fp,"%d \n",SSD_times); ++looptrial; }
Merci à tous;)

Hoe,

Une solution, pas forcément la meilleure :

Stocker les valeurs entrées dans un tableau, et le random te tirera l'indice à utiliser dans ce tableau. :)

je cloture et rouvre une autre discussion, ce problème étant résolu...
Merci à ceux qui m'ont aidé;)
